Abstract
A renormalisation group analysis of anomalous diffusion in a random medium with constrained long-range correlations is carried out to two-loop order. The crossover between the long-range correlated model and its short-range correlated counterpart is investigated and the dynamic exponent z is shown to be continuous at the crossover.Keywords
